광열 편향 빔에 의해 해결 단백질의 밀리 초 이하의 구조적 변화

Executive Industry Relevance

Photothermal beam deflection enables direct, label-free quantification of submillisecond conformational changes in proteins, providing unique insight into rapid ligand-induced structural transitions. This capability addresses a critical gap in early discovery and mechanistic de-risking, especially for targets lacking intrinsic chromophores or fluorophores. The method enhances predictive confidence in target validation and supports risk-adjusted portfolio decisions by delivering quantitative thermodynamic parameters inaccessible to traditional techniques.
